diplomsko delo

Abstract

Kibernetske grožnje so s pojavom interneta postale stalnica. Z varnostnimi ukrepi želimo izboljšati varstvo podatkov pred nezakonitim dostopom, uporabo, razkritjem, spremembo ali uničenjem. Nepridipravi si poizkušajo prilastiti tajne informacije z razlogom, da se finančno okoristijo. Pred njimi se ustrezno zaščitimo tako, da se seznanimo z varnostnimi tveganji in orodij za zaščito pred njimi. Pričujoče diplomsko delo predstavlja opis varnostnih nastavitev in uporabo orodij za pregledovanje in utrjevanje operacijskega sistema Ubuntu Linux. Ocenili smo ranljivosti prevzetih nastavitev tega sistema in preučili njegove varnostne luknje in pomanjkljivosti. Sistem Ubuntu Linux je prevzeto nameščen precej nezaščiten. To smo izboljšali s spremembo sistemskih nastavitev tako, da smo omejili dostop do sistema tujim uporabnikom. Namestili smo orodja, ki nudijo zaščito pred zunanjim omrežjem, in orodja, ki nam pomagajo iskati morebitno kompromitiranje sistema, če so te že zgodile.

Secondary title:	Hardening and monitoring of the Ubuntu operating system
Secondary abstract:	Since the arrival of the Web, cyber threats have become a commonplace. By applying certain security mechanisms, we aim to improve data protection against illicit access, use, disclosure, modification or destruction. Fraudsters aim to appropriate classified information for financial gain. The only way we can protect our data is by familiarising ourselves with these security risks and the tools needed to protect ourselves from them. This thesis presents a description of the security settings and the use of tools for inspecting and hardening the Ubuntu Linux operating system. We assessed the vulnerabilities of this system and examined its security flaws and shortcomings. Although Ubuntu Linux is relatively secure when installed by default, we improved it by changing its system settings to restrict foreign users from gaining access to the system. We installed tools that provide protection from external networks and tools to help us scan for potential system infections if these were to occur.
